Implementeringen av EU:s ramdirektivför vatten i kommunernas planarbete : En studie av kommunerna i Stockholms län

The European Water Framework Directive (WFD; 2000/60/EC) was incorporated into the Swedish legislation in 2004 through the ordinance Förordningen om förvaltningenav kvaliteten på vattenmiljön (SFS 2004:660). The objective is that all water bodies shall reach a good status by the year 2015. In Sweden the comprehensive plans of the municipalities can play a large role in reaching these goals. A comprehensive plan deals with the long term water and land use of the municipality, which can facilitate an early consideration of water management in the planning process of the municipality. In Sweden five river basin districts have been established in accordance with the Water Framework Directive.

In this essay I seek to examine how the Principle of Provenance can be discerned in the new activity-based wayof establishing an archival description. In which terms do authors of reports and works about archival descriptionspeak about provenance. Do they at all?In order to do so I have studied the history of the Principle of Provenance and what is to be its future ? theregulation from the Swedish National Archives, RA-FS 2008:4. I have also read the referrel that was sent out toSwedish authorities, universities and other archival institutions.

Fysisk aktivitet i ett livslångt perspektiv : En studie om lärares, i ämnet idrott och hälsa,syn på fysisk aktivitet i ett livslångt perspektiv

AimThe aim of this study has been to examine how health enhancement teachers in Montana, USA, view the value of physical activity from a lifelong perspective.In what way does the health enhancement teacher think the importance of physical activity from a lifelong perspective could be presented?What resources are available for teachers to present the value of physical activity from a lifelong perspective?MethodThe issue has been answered through qualitative interviews consisting of six health enhancement teachers, four women and two men, in Montana, USA. One of the teachers worked at an elementary school (for 30 years), three teachers worked at middle schools (20, 10 and 8 years of work experience) and two of the teachers interviewed worked at a high school (30 and 3 years).  ResultsThe majority of teachers feel that a wide variety of activities, adapted to an individual level, and the understanding of a healthy lifestyle are important in order for the teacher to present the value of physical activity from a lifelong perspective.The teachers felt they had sufficient material in order to present the value of physical activity, where the school budget provided the teachers with materials every year. In addition to the budget, all the teachers had 12 hours of professional development every year where they could attend conferences or their own choice of professional development.ConclusionWith the help in forms of professional development offered by the school, conferences, meeting with other teachers, and their own choice of development, the teachers instruction techniques could increase which could help the teachers to find the pupils? interest for different kinds of physical activities.KeywordsPhysical education and health, physical activity, SOC, sense of coherence..

Daglig verksamhet enligt LSS : Hur resonerar ett antal deltagare med intellektuella funktionsnedsa?ttningar kring sitt arbete?

This essay aims to examine the meaning work at daily activity centers gives people with intellectual disabilities and the questions these people consider necessary to ask in quality surveys. This has been done by interviews with twelve respondents in various daily activitiy centers within a private care company in the Stockholm area. The theories that has been used to analyze the empirical data is SOC - sence of coherence, stigma and empowerment. The result shows that the meaning of daily activity is to create and maintain social contacts, feeling important and needed by others and an opportunity to feel ?normal? and like everybody else.

Can increased activity recorded with help of activity monitoring sensor indicate an upcoming calving?

The purpose of this study was to find out if motion movements, e.g. number of lying bouts and lying time with a registered activity monitoring sensor can detect an impending calving and thereby be used as a measure and an indicator for an upcoming calving. For this, automatically step sensors were used and were attached to one of the cows? hind leg. The sensor registered the individual step and movement activity of the cow.

Video på bibliotek : en granskning av spelfilmsverksamheten på svenska folkbibliotek

This is the first investigation of the activity with feature film (video) in Swedish publiclibraries.Due to the Swedish copyright legislation, the activity with feature film in Swedish publiclibraries was not possible until an agreement was set between Kommunförbundet and SverigesVideodistributörers Förening in 1989.My investigation is based upon a form that I made in cooperation with Statens kulturråd.The form was sent to the main public libraries in the 286 municipals in Sweden. 250 (87 percent) of the public libraries answered the questions. 130 (52 per cent) of the libraries whoanswered had an activity with feature film.The main reason the libraries bought feature film, was that they hoped that feature filmwould attract new visitors to the library. The investigation also showed that high costs forhiring feature films has a negative influence on the lending of feature films..

Lärares erfarenheter av arbete med elever som far illa

The purpose of this study was to investigate the association between physical activity and perceived stress, energy and musculoskeletal disorders among office-workers and warehouse-workers and also to see if there were any differences depending on work-place and gender. The method that was used to collect data was three different validated questionnaires that measured stress and energy (the Stress-Energy questionnaire), musculoskeletal disorders (intensity and localization of pain, a Pain Drawing questionnaire with a VAS-scale) and physical activity (IPAQ ? the short version). Eighty-eight workers participated in the study. Forty-seven of them were office-workers and forty-one were warehouse-workers.

Skalkonstruktion : Med inriktning mot hållfasthet och dämpning av ljud

The sound part is mainly practical and is dependent on concepts that have been tested through measuring with a sound level meter. The design part is more theoretical and has been verified with CAD models and finite element analysis.With a sound damping hood on the compressor the sound level is reduced with up to four dB. An optimized absorbent for the compressor space gives a reduction with three dB. By using the insulation for the heat water tank as absorbent we can see a sound reduction on the lover octave bands. A reduction like this is elsewhere hard to achieve as at it requires thick absorbents.By changing the today?s insulation to the heat water tank to a form of polystyrene polymer insulation the weight from the heat pump above can be transferred to the stable heat water tank.

Cypern-målet : Upplägget, lagstiftningen och konsekvenser

The financial result of a transfer of ownership or external sale is to a great extent depend-ent on how the transfer is implemented and how the tax rules apply. The applicability of the Swedish tax rules regarding transfer of ownership in closely held companies largely de-pends on the interpretation of the prerequisite, equal or similar activity, which can be found in section 57, clause 4 of the Swedish Income Tax Act.The ruling made by the Supreme Administrative Court in RÅ 2010 ref. 11 changed the concept of equal or similar activity. The ruling lead to that the shares in a closely held com-pany was qualified due to that the capital from the original company had been transferred to the operating company. According to the ruling the original company had been split into several companies, thus was the companies considered to carry out equal or similar activity.

Removal efficiency of perfluoroalkyl substances (PFASs) in drinking water : evaluation of granular activated carbon (GAC) and anion exchange (AE) using column tests, and the effect of dissolved organic carbon

Poly- and perfluoroalkyl substances (PFASs) are a group of environmental contaminants that have gained increasing attention due to their potential to bioaccumulate, environmental persistence and potential toxicity. PFASs have been found in surface water, sediment, air, soil, sludge and ice caps globally, as well as in wildlife and humans. Furthermore, PFASs have also been detected in drinking water, leading to raised concerns for human health, since drinking water is one of the most significant sources of PFASs for the general population. Conventional water treatment techniques have shown to be ineffective removing PFASs, highlighting the importance for further research to develop efficient removal techniques. The aim of this study was to investigate the removal efficiency of PFASs in water using two treatment techniques; granular activated carbon (GAC), type Filtrasorb 400®, and anion exchange (AE), type Purolite A-600. Additionally, the effect of dissolved organic carbon (DOC) on removal efficiency was studied.

Förutsättningarna för ett parallellt generation IV system vid svensk nybyggnation av kärnkraft.

A new build in the Swedish nuclear power system would entail increased re-quirements for the proposed repository, which is adapted after the reactors of today. With a fast reactor, capable of burning nuclear waste, operating in parallel with the light water reactors, the increased requirements on the repository could be reduced.In this thesis, simulations of a light water reactor and a fast reactor have been performed by using the Monte Carlo code Serpent to investigate the changes in the fuel inventory. The light water reactor in the study is a boiling water reactor and the fast reactor of the type sodium-cooled fast reactor and they have been used for three different operation scenarios.By studying the fuel composition and the results from the simulations of the three scenarios conclusions can be drawn. Conclusions regarding the change of the fuel inventory and decay heat in Clab as well as the interim storage facility and in the repository. Depending on the operation alternative the changes dif-fered significantly and especially regarding the mass of burned actinides for different fuels in the fast reactor.The lowest increase of fuel assemblies was meet when using 50 years old fuel with 20MWd/kg U burnout and 2,0 % enrichment for start up of the fast reactor and 30 years old fuel assemblies with 50MWd/kg U burnout and 4,7 % enrichment for the further operation of the reactor.The increase of the number of fuel assemblies was 3174, which is equivalent to 641tons of heavy metal.
